4 Claims.

This invention relates to keying connecting devices for assembling and supporting a load.

This invention has utility when incorporated in hook mountings on girder structures adapted to project through a pan or holding form for a pour or cast of concrete and to be keyed therewith to sustain the concrete during setting and even for thereafter ready removal of the form.

Referring to the drawing:

Fig. 1 is a side elevation, with parts broken away, showing an embodiment of the invention to hold the pan form for a pour of concrete;

Fig. 2 is a section on the line II-II, Fig. 1, showing the clip device in mounted position as to a girder and keyed to the form pan therebelow;

Fig. 3 is a detail View of the relatively movable hook of the clip of Fig. 2; and

Fig. 4 is a View of the flat blank of the clip body.

In building construction say for concrete form of slabs for floors, ceilings, or roofs, such horizontal structures in their extent may have relatively deeper portions as girders I, herein shown as of skeleton form, having along the base portion thereof parallel rods 2, 3, as girder element portions forming longitudinally extending projections or seats.

Sheet metal blank body 4 has integral therewith overhanging hook 5. Tongues 6, 1, extend downwardly in the plane of the hook 5. Lateral projection or extension 8 is from each tongue 6, 1. These extensions are away from each other. Above these extensions 8 there are downwardly tapered guide portions 9 to the respective tongues. Rising from the body 4 adjacent the tongue I is portion H1 having finger I l leaving clearance [2 as to shoulder 13 opposite the guide 9 as adjacent the tongue 7. Opening I4 is in this body 4 provides a way through which short upwardly bent arm [5 may extend to bring seat or angle portion l6 into holding engagement with the opening M as riser I! therefrom carries hook portion l8. This hook portion 18 is accordingly opposite the hook portion 5, which, as extending toward each other, may engage the respective rods 3, 2, of the girder structure and thus provide a substantial support for this clip to be anchored by the pour or cast of concrete against removal.

However, before the pour these slips may have the respective tongues project through opening or openings IS in pan or mold element 20. As these tongues 6, 1, project through this slot or opening in the pan or mold element, the extensions 8 may be deflected laterally out of the plane of the tongue of the element as to the hook 5, tongues 6, l, and body 4, whereby the extensions 8 become offsets 2| effecting keying against shifting of the pan or mold cast holding portion. These clips may be located at the position wherein the respective pans have the slots and in the bridging or assembly to meet special conditions there may be relative telescoping between the pans or insertion of bridging sections 22.

As the form is thus in position, a pour of concrete may be made to envelop the girder skeleton I, 2, 3, as well as anchor the clips therewith and provide between the girders the relatively shallow floor, ceiling or roof portion. As this pour of the concrete is sufiiciently set, in the event it is not desired to leave the pans with the poured structure, it is only necessary to bend the extensions 2| from the out-of-plane position as to the tongues 6, 1, into such plane and the pans may be readily dropped clear of the pour. These clips as anchored in the pour may have the tongues left or such tongues removed. In the event the tongues be left, openings 23 may carry rods or other anchorage, say for the location of a composition, metal ceiling, supporting lath, or other plaster holding means for running the ceiling portion desired.

In this assembly of the clip on the girder structure, as the hook 5 is in place and the hook it is so shifted, there is not hazard for any ready release, even as strains may be placed upon the clip, say as shifting pans to strike or be guided into position by the inclines 9. This may not effect disconnection, for the finger H has been deflected to form stop 24 and the hook I 8 may thus not swing in the hinge opening I 4. The upward bend l5v in providing the seat l6 prevents transverse or otherwise working out of this relatively movable hook as to the clip. This twopart clip is thus firmly retained in its assembly relation as a substantial support.

This application is a continuation-in-part of application for United States Letters Patent, Ser. No. 204,110, filed April 25, 1938, for Suspended construction.

What is claimed and it is desired to secure by United States Letters Patent is:

1. A clip having an integral hook, and a pair of parallel tongues in the plane of said hook and having opposite extensions, said clip having a relatively rockable hook, said clip having a finger to limit the rocking of said latter hook, said hooks being adapted oppositely to embrace a girder structure, said extensions being deflectable t0 hold an element on the tongue against clearing said tongue.

2. A girder structure having a seat, a clip adapted to overhang the seat and depending as an overhanging tongue having a lateral extension, a plate element adapted to act as a form for masonry, said plate element having an opening to receive the tongue, said extension being deflectable as to the tongue into out-of-register position as to the opening to sustain the element.

3. A girder, a pan having an opening therethrough, a sheet metal clip adapted to be assembled between the girder and pan, said clip having a hook for overhanging the girder, and having a tongue adapted to pass through the opening in the pan, said tongue having an extension deflectable out of said plane for into outof-register position as to the pan, thereby to cause the clip to assemble the pan with the girder.

4. A clip having an integral overhanging hook, and therefrom an extension below and beyond the hook provided with an openingtherethrough, and a relatively rockable additional hook directable toward the overhanging hook and mounted in the opening as a bearing, said pair of hooks being adapted to engage a girder therebetween with the extension connecting the hooks below the girder.
